This course has been approved by the LSP Board of Registration for 1.0 hour of Technical/Non-DEP continuing education credits (#1693A). This presentation was originally offered as a live webinar in May 2020 (#1693).

Course Description:

The course will discuss 1,4-dioxane as a contaminant of emerging concern that is increasingly detected in groundwater, surface water, and drinking water. 1,4-dioxane is primarily associated with chlorinated solvent sites where it is used as a stabilizer primarily for trichloroethane; however, there are many other uses of it resulting in impacts outside of chlorinated solvent spill sites. The presentation will outline the properties of 1,4-dioxane as they impact remediation. Case studies will be used to illustrate both ex-situ and in-situ remedial options to treat 1,4-dioxane. Remedial options to be discussed include reliable, proven technologies such as oxidation and sorption, but also evolving technologies such as thermally enhanced removal, bioremediation, and phytoremediation.
